The river Niger flow regime is characterized by low flow situation at the Upper Niger and Lower Niger sub-catchments, and flood situation is observed at the Inner Delta and Middle Niger sub-catchments due to the continuation of the Guinean flood (Black Flood) that began since October 2020.
The floods occurred at the end of December 2020 in certain localities of the city of Niamey are linked to the degradation of dike in certain points during the exceptional flooding of August and September 2020.
